RRB NTPC Graduate CBT 1 2024 PYQs

Concept: Find the position change of each letter.

1. RWKA → TULZ: $R+2=T$, $W-2=U$, $K+1=L$, $A-1=Z$.
2. Check VSMY → XQNX: $V+2$, $S-2$, $M+1$, $Y-1$ ✓.
3. ZOOW: $Z+2=B$, $O-2=M$, $O+1=P$, $W-1=V$ → BMPV.

Trick: Pattern $+2,-2,+1,-1$; after Z comes A again (circular).

Answer: (A) BMPV

Concept: Fix the definite positions first, then place the others.

1. O = 4 and Y is immediately below O → Y = 3.
2. Two people between O and P → P = 1 (floor 7 does not exist).
3. Only M between O and N → M = 5, N = 6 (M cannot be 3 as Y is there).
4. The remaining person Z lives on floor 2.

Trick: Start with the person whose floor is given, then use “immediately” clues.

Answer: (B) Z

Concept: Seven seats in a row facing north: left to right = 1 to 7.

1. Only J is to the left of Q → J = 1, Q = 2.
2. Four people between J and I → I = 6.
3. Only O between P and K, and P not next to I → P = 3, O = 4, K = 5.
4. Remaining L sits at 7, the extreme right end.

Trick: “Only X to the left of Y” immediately fixes both at positions 1 and 2.

Answer: (C) L

Concept: Opposite letter pairs: positions add up to 27 (A–Z, B–Y, …).

1. ZIL → ARO: Z↔A, I↔R, L↔O (each letter replaced by its opposite).
2. GRZ → TIA: G↔T, R↔I, Z↔A ✓.
3. XMS → CNH: X↔C, M↔N, S↔H ✓. Others fail (e.g. J↔Q, but P↔K not J).

Trick: Opposite of a letter $=27-$ its position.

Answer: (D) XMS : CNH

Concept: Total = rank from top + rank from bottom − 1.

1. Total $=24+55-1$.
2. Total $=78$ students.

Trick: Subtract 1 because the person is counted twice.

Answer: (C) 78

Concept: Draw the least-overlap Venn diagram; a conclusion follows only if it is true in every possible case.

1. All crabs are inside ties; some ties are hooves – but the hooves part may lie outside crabs.
2. So “Some hooves are crabs” (II) is not certain.
3. Vents are linked only with hooves, so “Some vents are crabs” (I) is not certain either.

Trick: “Some” + “some” never gives a definite conclusion.

Answer: (C) Neither conclusion (I) nor (II) follows.

Concept: Replace the signs as given, then apply BODMAS.

1. $1568-16+4÷5\times 22$ becomes $1568÷16-4\times 5+22$.
2. $=98-20+22$.
3. $=100$.

Trick: Rewrite the whole expression first, then calculate – avoid mixing old and new signs.

Answer: (C) 100

Concept: Interchange + ↔ − and × ↔ ÷, then use BODMAS.

1. $52÷15-189\times 9+117$ becomes $52\times 15+189÷9-117$.
2. $=780+21-117$.
3. $=684$.

Trick: Do ÷ and × first: $189÷9=21$, $52\times 15=780$.

Answer: (A) 684

Concept: The change from the 1st cluster to the 2nd must be the same on both sides of ::.

1. Try option D: PMB → RND: $P+2=R$, $M+1=N$, $B+2=D$.
2. Apply the same to QRX: $Q+2=S$, $R+1=S$, $X+2=Z$ → SSZ = %.
3. Both sides follow $+2,+1,+2$ ✓.

Trick: Check the right-hand pair from the options quickly; only one gives a consistent rule.

Answer: (D) # = PMB, % = SSZ

Concept: Look at the differences between consecutive terms.

1. $801-1=800$, $800-3=797$, $797-5=792$, $792-7=785$.
2. Differences are odd numbers 1, 3, 5, 7, so next is 9.
3. $785-9=776$.

Trick: Also $801-n^2$: $801-0,801-1,801-4,801-9,801-16,801-25=776$.

Answer: (C) 776

Concept: Check the alphabet gaps between consecutive letters.

1. SUP: S +2 U, U −5 P
2. NPK: N +2 P, P −5 K
3. GID: G +2 I, I −5 D
4. PRV: P +2 R, R +4 V — breaks the pattern

Trick: Write position numbers: S19 U21 P16 → +2, −5.

Answer: (C) PRV

Concept: Fix the certain positions first (top = 1, bottom = 7).

1. Only A above D → A = 1, D = 2; four between D and F → F = 7.
2. C and G (two between) fill 3 & 6; E–B pair takes 4–5.
3. If G = 3, G is immediately above E ✘ → C = 3, E = 4, B = 5, G = 6.
4. Below E: B, G, F = 3 boxes.

Trick: Always place the "only X above" clue first — it fixes the top.

Answer: (D) 3

Concept: Apply the same change to each part.

1. WJ15 → UN11: W −2 = U, J +4 = N, 15 −4 = 11
2. QH8 → OL4: Q −2 = O, H +4 = L, 8 −4 = 4
3. RI3 → R −2 = P, I +4 = M, 3 −4 = −1 → PM −1

Trick: Rule: (−2, +4, −4).

Answer: (D) PM −1

Concept: A word common to two sentences gets the code common to both.

1. ‘poet’ appears in both: joy lab poet / poet win union.
2. Common code in ‘to dl dh’ and ‘dl fo kb’ is dl.

Trick: Common word ↔ common code.

Answer: (A) dl

Concept: Arrange the digits in ascending order and count from the left.

1. Digits of 8142769: 8, 1, 4, 2, 7, 6, 9
2. Ascending: 1 2 4 6 7 8 9
3. Fourth from left = 6

Trick: With 7 digits, 4th from left is the middle (median) digit.

Answer: (A) 6

Concept: Track net east–west and north–south movement (left/right turns change facing).

1. West 12 → left (S) 6 → left (E) 4 → right (S) 2 → right (W) 3 → left (S) 3 → left (E) 11.
2. East–West: $-12+4-3+11=0$
3. North–South: $-6-2-3=-11$ (11 km south of A)
4. So P is 11 km south of A → drive 11 km north.

Trick: Horizontal moves cancel exactly, so the answer is just the total southward distance.

Answer: (C) 11 km north

Concept: Compare each letter of the first cluster with the matching letter of the second.

1. OP → KL: −4, −4
2. IJ → EF: −4, −4
3. MN → IJ: −4, −4
4. LD → KH: −1, +4 — different

Trick: In the group, the first pair is also consecutive letters; LD is not.

Answer: (A) LD - KH

Concept: Find the shift for each letter (cyclic alphabet).

1. DREAM → ZNAWI: every letter −4 (D→Z, A→W wraps around).
2. DANCE → ZWJYA: again −4 each.
3. DOUBT: D→Z, O→K, U→Q, B→X, T→P = ZKQXP

Trick: −4 = move 4 steps back; after A comes Z.

Answer: (D) ZKQXP

Concept: Interchange the signs, then use BODMAS.

1. $56-12\times 4÷9+5$ becomes $56+12÷4\times 9-5$
2. $12÷4=3$, $3\times 9=27$
3. $56+27-5=78$

Trick: Rewrite the whole expression first, then solve — never swap mentally.

Answer: (C) 78

Concept: Track each letter position separately.

1. 1st letters: V T R P N (−2)
2. 2nd letters: Q O M K I (−2)
3. 3rd letters: L J H F D (−2)

Trick: All three positions move −2 → NID.

Answer: (A) NID
